128 Used software: ESA-Prima Win • Total steel weight: ± 735 tons • Total length: 10.5 m – 80 m – 10.64 m Width: 19 m About the project The city of Bamberg in Germany wanted to rebuild the “Luitpoldbrücke” over the Main-Danube-Canal. This bridge is the access to city centre. The old bridge is removed and replaced by a “3-feld bridge” existing of 2 concrete approach spans (±10.5 m) and a midspan of steel 80 m. The arches are build up with 3D-braced arches composed of arched tubes (Ø 406, 4). The bridge deck is hung up at the arches by a radially placed hanger (Ø 100). The construction consists of two main beams connected by I-shaped, in height changing, cross members. The mean beams consist of two above each other placed tubes (Ø 406, 4) connected with a central vertical plate. The node that connects the arches with the last cross member and the main beams is realized with cast steel in the form of a snail’s shell. For the erection by launching the piles of the old bridge are used and demolished afterwards. Use of ESA-Prima Win Description of technical questions to be solved with ESA-Prima Win Both, for the camber and deformation calculation and the erection engineering of the bridge, ESA-Prima Win was used. The complete 3D-model was put with bars and different building stages were set. For the calculation in erection situation each bridge member was given a buckling factor based on the rules of EC3. The beam check was then made by EC3 Steel Check of ESA-Prima Win. The buckling control of the arches was done in three ways. The first method was done with EC3-Steel Check of ESA-Prima Win. The second method was based on the calculation of the axial critical buckling force, which was compared by ESA-Prima Win with Bowstring Bridge of Bamberg, Germany The city of Bamberg in Germany wanted to replace the old “Luitpoldbrücke” across the Main-Danube-Canal. This bridge is an important access to city centre. The old bridge has been removed and replaced by a “3-feld bridge” existing of 2 concrete approach spans (±10.5 m) and a steel midspan of 80 m. The arches are build up with 3D-braced arches composed of arched tubes (Ø 406, 4). The bridge deck is hung up at the arches by a radially placed hanger (Ø 100).

The mean beams consist of two above each other placed tubes (Ø 406, 4) connected with a central vertical plate. The node that connects the arches with the last cross member and the main beams is realized with cast steel in the form of a snail’s shell.
